The Ash pan itself gets wonky when hot. or becomes out of square . switching out pans is a good 24/7 idea.. thin 1/4 in strips on bottom pan would keep it flat n str8 when hot.. Cracking Ash door brings up flames IMED.. It takes time to build up heat in the progress .. I bet the New Steel stove heats up Fassssst.. Woodstock been out of Ash rakes for 8 months now or so.. cant get one. gonna just bend an extra cast fireplace shovel..
Hmmm... I've not had a problem with the ash pan going "wonky" - but then perhaps this is because I generally change out when the stove is (relatively) cool - for example this morning the stove was reading about 200 surface and while I had coals in the stove, there was not a large pile (more than enough to re-light though).
Cracking the ash door to light up? This is a very bad idea. IF you are needing to do this in order to get up to temp then something is wrong here - either your draft is very weak or your wood is not dry enough. Seriously - you should fix whatever the issue is and your enjoyment of the PH will go up I'm sure. Case in point - this morning after changing the ash pan out I loaded up with 12 splits (filled but not 'packed' (I say this so you get a sense of the size splits I'm using). Coals had been moved to the front of the stove. After loading I closed the door and opened air full. Within 1-2 minutes I had good flames and reduced air to about 75%, then let it cruise to 250 in about 10 minutes. I had stove cooking along with good secondaries, air down to a crack, and stovetop around 500 (needed the heat, cold morning) within 30 minutes. Perhaps slower than a pure steel stove, but not anywhere near "slow" enough to take the risk of opening the ash pan door.
